How to purchase a fundamental car tools

Every car owner should have the basic tools to keep a car running in the house or do minor repairs. Should provide additional protection tools with insulated handles. Keep a box of tools, they can be kept dry,and to remove grease, dirt, especially in water after they are used. In hardware stores and auto supply Auto Tools, you will find a lot of tools.

1
Clarify the extent of your ability. There is no need to purchase a range of automotive repair tools, if your maintenance knowledge is limited. However, this does not mean that a novice minor damage can not be repaired.

2
Start simple. Buy a set of adjustable wrenches and OBD MATE OM520 , a socket and jumper cables. Cleaning supplies and automotive stocks only deal with oil spills and oil hand towels and wipes.

3
Act like a pro. Even limited knowledge, you can buy a continuity tester to check the circuit. They are quite cheap. If you feel comfortable hammering out the bells and small body, buy rubber hammer repair.

4
What is necessary to please an auto mechanic. Like a chef and his knife, a carpenter and his hammer, auto mechanics usually have a couple of small, cheap car v-Checker A501. Ask around and see if you start your collection.
Tip:
Do not under a top car. Jack is not very stable, and is used only for replacement tires. Car lift or wheel ramp design work out of the car.

How to Tell if the car battery is short-circuited

A car battery is a typical lead-acid type of energy storage device, consisting of the battery's positive terminal side from the side of a negative terminal of the battery 6 independent cells. Is the energy of each cell stored a voltage of about ADD71, which means that a fully charged battery with all normal operating cell will display a stored voltage of about 12 volts. Later, when a full overnight charge, the total voltage battery voltage reading 10.5 volts or less, which is a strong indicator that a cell has been damaged, or that itself and the other between its sides has a very short. To determine whether the battery is a poor contact or short-circuit of the battery, there is provided an appropriate charging and then test the battery charge cycle is complete.

1
Disconnect the car battery, the battery charger from the car and the car next to it. The charger cable to the negative battery negative terminal, and then connect positive positive terminal of the battery charger cable is connected to. , And then insert a fully charged overnight charger, and set it to allow charge to happen.

2
Close the battery charger, then disconnect the power Multimeter ADD81. Quickly remove the battery cable terminal.

3
Turn on your digital multimeter set to measure 20 volts DC. Touch the black test probe tip to the negative terminal of the battery, and then touch the red test probe tip to the positive terminal of the battery. Allow a few seconds, the voltage readings displayed on your instrument. If the voltage reads 12 volts or slightly more, your battery is healthy. However, if the voltage reading of 10.5 volts or lower,your bad battery cell or shorted together two cells.
Tip:
If your battery is not "maintenance-free" type, and the top of the removable cover, remove the cover and shine a flashlight into every cell, and then observe whether the cells are dry in the cell reservoir. If this is the case, the cell is filled to just below the pour hole of the lower edge, and in accordance with the above steps again. Improper maintenance of the fluid in the battery may damage a cell, causing it to short with another nearby cell or stop working altogether, because it is unable to perform the chemical storage process.
Car battery charging in a well-ventilated place, in the process of charging may cause the ADD71 Sensor Simulator to release hydrogen, which may cause a spark bombings.

How to solve the CD player

Although you will rarely be able to repair your own Noise Finder ADD3500, you may be able to diagnose the problem. This can help you decide whether repair.

1
Check all connections, for example, from the player to the amplifier or receiver and receiver speaker. Check and clean RCA jacks and cable, and try different input amplifier or receiver.

2
Clean the lens. Use only a special CD lens cleaner, then follow the instructions carefully.

3
Check wire components. If the disc is not recognize or will not play, often skipping occurred in the CD-ROM obtained Circuit Tester ADD210 can stay in one place and can not find the right track, or Clean the lens does not work. Dust and lint may be interrupting its function.

4
Laser head assembly, service personnel check if the mobile component seems to be intact, free of debris.

5
Check whether the stuck CD drawer open or closed or only partially open or close. If you do not have a gear and belt replaced.

6
Lubrication of the gear, if the CD player can only play a specific point on a particular track or disc.

7
Looking for broken plastic parts, such as gears and clips.

8
Look for loose or broken ADD71 Sensor Simulator.

9
Replace the power supply, if your CD player from overheating.

10
If your player will not recognize the CD-ROM, Make sure you insert the CD, no scratches, and the lens is clean.

How to solve the Grand Prix ABS light and traction control lights

Anti-lock braking system and traction control systems are used in your Grand Prix ABS wheel speed sensor and control wheel spin valve assembly. The ADD9000A to monitor wheel speed sensors, to reduce it is detected is close to lock the brake pressure on the wheel. Traction control systems monitor the same wheel speed sensor, the brake pressure for more than any wheel acceleration feeling. These systems are the vehicle computer diagnostic functions through the use of scan tools and automotive diagnostics.

1
Check the tires for proper wheel size and check the fluid level of the master cylinder. Improper tire size, such as two different dimensions, causes the wheels to turn at different speeds, and may be set to a false code, the computer detects this as a potential wheel lock. Low fluid level in the brake master cylinder, will lead off, to prevent air from entering the brake system ABS and traction control system.

2
Turn off the ignition switch and the scan tool connector into the vehicle ADD510 Infrared Thermometer. With instrument steering column near the OBD-II diagnostic connector is located in the driver's side of Grand Prix. According to the instructions provided with the scan tool, the ignition key and retrieve trouble codes. In most cases, you will select the "read code" from the menu on the screen, or press the "read" button, the previous scan tool to get the code. If the wheel speed sensor fault code indicates or step 5, if the code indicates a solenoid valve failure, go to step 2.

3
Select the "data" from the menu on the screen to scroll through the list until the wheel speed sensor data is displayed on the screen. Test drive the car, while monitoring wheel speed signal, fault code scanning tools. If the wheel speed signal is different from the other wheel speed signals, testing the resistance of the sensor.

4
Unplug the failure of the wheel speed sensor, the wheels of each wheel with the back of the bearing and ADD71 of a sensor located in the Grand Prix and tested using the digital volt / ohm meter, set to read the resistance of the resistor. A good wheel speed sensor resistance to be1k of ohms + / - 10%. Replace the sensor if the meter shows 0 ohms, infinite ohms, or resistance 1k ohm + / - 10%.

5
Check the fuse fuse box, dashboard and under the hood. ABS and traction control systems are marked on the the fuse body fuse holder. Replacement of any faulty fuse, and then proceed with the test. Unplug the regulating valve assembly is located in the driver's side of the Noise Finder ADD3500 near the master cylinder to test the resistance of the solenoid valve to use your digital voltage / ohm meter. The replacement regulator valve assembly, if the 0-ohm resistor infinity, are assembled.

How to test a automotive relay switch

The automotive relay apparatus is used to control a high electric current, such as electric cooling fan, or a / c compressor clutch having a low-Circuit Tester ADD210 switch or computer circuitry. This makes use of the lightweight cabling and switch, as well as computer control possible in today's cars and light trucks. It can be seen, this additional weight saver option in improving the fuel mileage.

1
Find the relay, refer to your service manuals. If you do not have a specific service manuals for your vehicle, you can get an web format. Get out of this. Specialty shops, it includes the same information, it is low cost, online subscription format.

2
disconnect the relay, open the ignition switch to the run BENZ W164 CAN FILTER. Then, the test relay power and grounding type plug. Looking in the back of the relay, you will notice that two runs to plug four wire diameter is greater than the other two. These are in the the high current circuit interconnection. Everyone should are vested with authority when the key is that there should be terrestrial and the others are. If no power supply, check the fuse, if there is no reason to check device the relay control.

3
Test residual two power and ground lines. A conductor to be grounded, and, if the circuit is a computer controlled, only the ground with the key. Will carry the rest of the line, if it is a computer-controlled, in the ON position, the most ADD210. If there is no ground to ensure that the computer on the ground conditions have been met. These conditions can be in your service manuals. If the conditions are met, there is no existence of a ground, the computer fails.
If there is no power supply power cord, check the fuse and switch.
